Résumé
The city of Quebec is built on a promontory, oriented south-eastwards
along the northern shore of the St.Lawrence River. Since 1775, 53
landslides occurred, causing 88 fatalities and injuring 70 people.
Moreover, about twenty houses were destroyed and about fifteen were
damaged. The analysis of the landslide database makes it possible
to extract the main instability factors, that are integrated in an
original GIS-based method. The proposed method enables to assess
the hazard along a selected profile. The simulated landslide frequency
not only shows a good agreement with the observed one, but also makes
it possible to individuate sections with a high landslide susceptibility.
Moreover, frequencies can be calculated, that furnishes the base
for risk calculations.
